The invention discloses a spray drying equipment for chemical fertilizer production and a chemical fertilizer production method, and relates to the technical field of spray drying equipment. The invention includes a feeding mechanism, a cold air supply mechanism, a negative pressure exhaust mechanism, a hot air supply mechanism, a cyclone dust collector, a pulse bag filter and a spray drying mechanism; one end of the air inlet of the cold wind supply mechanism and the hot wind supply mechanism is connected with an air filter through a pipeline. One end of the discharge port of the feeding mechanism is connected with the pump body; one end of the discharge port of the pump body is in rotational communication with the spray drying mechanism through the feed pipe. The present invention changes the static structure of the traditional drying equipment into a dynamic structure through the differential reverse rotation design of the atomizing nozzle assembly and the inner shell, and can effectively reduce the fixed-point contact between the particles and the inner shell through the dynamic structure design Degree and fixed-point contact time, through the realization of the above effects, and then effectively reduce the adhesion probability of particles inside the device.
Description
technical field [0001] The invention belongs to the technical field of spray drying equipment, and in particular relates to a spray drying equipment for chemical fertilizer production and a chemical fertilizer production method. Background technique [0002] The spray dryer can be used in a wide range. According to the characteristics of the material, it can be dried by hot air or by cold air. A large number of products with very different characteristics can be produced by this machine. Commonly used are: polymers and resins, dyes, pigments, Ceramics, glasses, rust removers, pesticides, carbohydrates, dairy and egg products, tannins, slaughterhouse by-products, blood and blood products, detergents and surfactants, fertilizers, organic compounds, inorganic compounds , instant food, medicine, etc.; the advantages of spray drying: it can make the materials of solution, emulsion, suspension and paste liquid into dry powder, fine and medium particle products after spray drying. ...
